It looks like the HTA was updated on June 9 - see Law Document English View. It appears the section that made HOV access temporary has been deleted as the previous document you to say "Note: On July 1, 2016, paragraph 9 is revoked. See: O. Reg. 236/10, ss. 2, 3; O. Reg. 99/15, s. 6." But that section is now gone! Green plates are now covered in section 7. Taxi or limo access to HOV lanes is still allowed but that is scheduled to be revoked on Jul 1, 2018.
